Dispersant (Dispersant) ndi mawonekedwe yogwira ntchito ndi katundu awiri osiyana, onse lipophilic ndi hydrophilic.The olimba ndi madzi particles kuti n'zovuta kupasuka mu madzi, zingalepheretse kukhazikikamo ndi condensation wa particles ndi kupanga amphiphilic reagent zofunika kuti khola kuyimitsidwa.

Ntchito ya dispersant ndi ntchito wetting dispersant kuchepetsa nthawi ndi mphamvu zofunika kuti amalize kubalalika ndondomeko, bata obalalika pigment kubalalitsidwa, kusintha pamwamba zimatha pigment particles, ndi kusintha kayendedwe ka pigment particles.Zimaphatikizidwa muzinthu zotsatirazi:

1. kusintha luster, kuwonjezera zotsatira za kusalaza luster kwenikweni chofunika kwambiri zimadalira ❖ kuyanika pamwamba kuwala kubalalika (ndiko kuti, flatness ena angakhale., Inde, ayenera kusankha ngati yosalala mokwanira, osati kuganizira chiwerengero cha particles mbadwa, mawonekedwe, ndi kuganizira kuphatikiza kwawo), pamene tinthu kukula ndi zochepa kuposa kuwala chochitika (mtengo wosadziwika), ntchito refraction kuwala, kuwala si bwino, chivundikiro chomwecho mphamvu amadalira kubalalitsa amapereka chivundikiro chachikulu. mphamvu sizidzawonjezeka (kupatula mpweya wakuda makamaka ndi kuyamwa kuwala, organic pigment kuiwala).Zindikirani: kuwala komwe kunachitika kumatanthauza kuchuluka kwa kuwala kowoneka sikwabwino;koma dziwani kuti kuchepa kwa chiwerengero choyambirira cha tinthu tating'onoting'ono ndikuchepetsa kukhuthala kwapangidwe, koma kuwonjezeka kwa pamwamba kudzachepetsa kuchuluka kwa utomoni waulere, ngakhale pali malo oyenerera, koma kupaka ufa siwochepa kwambiri. .

2. kupewa zoyandama mtundu tsitsi maluwa.

3. Sinthani mphamvu yamtundu kuti mumvetsere mphamvu yamtundu mu makina osintha mtundu siwokwera kwambiri.

4. Chepetsani kukhuthala ndikuwonjezera kuchuluka kwa pigment.

5. kuchepetsa flocculation ndi chonchi, koma woonda ndi tinthu pamwamba mphamvu, apamwamba, apamwamba adsorption mphamvu ya dispersant, koma mphamvu adsorption wa dispersant zingachititse chokhwima ntchito ❖ kuyanika filimu.

6. Chifukwa choonjezera kukhazikika kosungirako ndizofanana.Pamene mphamvu yokhazikika sikwanira, kukhazikika kosungirako kumakhala koipitsitsa (zowona, kuchokera pa chithunzi chanu).

7. onjezani mawonetseredwe amtundu, onjezani machulukitsidwe amtundu, onjezani kuwonekera (organic pigment) kapena mphamvu yakuphimba (inorganic pigment).

HD605 kunyowetsa dispersant kumathandiza moisten ndi kukhazikika pigment, kuteteza mtundu akuyandama ndi pigment kukhazikikamo, kukhalabe khola pigment chophimba mphamvu ndi mtundu mphamvu posungira, pamene kuonetsetsa pazipita kuchuluka kwa mtundu ndi osachepera masitepe akupera.Chifukwa zowonjezerazi zimatha kuchepetsa mamasukidwe akayendedwe ndikukwera mpaka kuchulukira kwa pigment kwambiri zikabalalika, zopaka utoto ndi pigment concentrate slurry zomwe zimapangidwa zimakhala zotsika mtengo.HD605 ikulimbikitsidwa kuti ipange utoto wamadzi.Kwa zokutira zotetezedwa ndi dzimbiri zamadzi, ndiyenso chinthu chomwe chimakondedwa.Itha kukwaniritsa zofunikira zamphamvu kwambiri za kuwala ndi rheological.Mndandanda wa HD605 ndiye msika womwe ulipo pamsika wopanda ethoxyalkyl phenol pamitundu yonse yosungunulira komanso chilinganizo chamadzi.M'dongosolo la UV, HD605 ndi yoyenera kwa mitundu yonse ya inki ndipo mankhwalawo alibe acetoxyalkyl phenol.
